A method of carrying out a self-configuration process in respect of a network element in a cellular wireless network including the steps of: generating first configuration parameters at a domain manager level; determining required second configuration parameters which are not to be generated at the domain manager level; notifying a network manager level of the first configuration parameters and the second configuration parameters to cause this level to generate and provide the second configuration parameters and to provide them to the domain manager level; and using the first configuration parameters and the second configuration parameters at the domain manager level to configure the network element.
